Gustav Haensel

Private life

Gustav Haensel was married to Jerta Pienitz from 1868 and had two sons, Heinrich Moritz Gustav (1877–1945) and Otto (1881–1941, son-in-law of Bruno Steglich ).

Companies

His father, the pharmacist Heinrich Haensel, had founded a "factory for essential oils and essences" in 1841, the Heinrich Haensel company in Pirna on the Elbe, which emerged from an existing material, tobacco and paint business through takeover.

In 1866 Gustav Haensel joined this company as a junior boss and partner. The business with the production of essences and aromas from essential oils for food, luxury goods and for industry flourished. In 1867 a new chemical factory was built on what is now Clara-Zetkin-Straße (previously Waisenhausstraße). In 1877 the company founder withdrew from the company and left the company to Gustav Haensel and his brother-in-law Rudolph Albert Bauer. The company was world famous at the end of the 19th century and sold its products through a worldwide network of agents. The factory was expanded in 1889/90; there was also a branch in Aussig from 1898/99 to around 1910 , which the son Heinrich Moritz Gustav Haensel managed from mid-1904 to April 1907. After Gustav Haensel's death in 1923, his son Otto, who had been with the company since 1905, took over the business. In 1935 the company was taken over by CW Gerberding ( Dragoco Gerberding & Co. GmbH ) and relocated to Holzminden . The company Heinrich Haensel Pirna GmbH & Co. KG, based in Holzminden, existed as a wholly-owned subsidiary of Symrise and was only dissolved in September 2007.

The company made a name for itself in particular for researching and identifying the ingredients of essential oils. The scientific investigations were recorded by the Haensel company in the quarterly annual reports ( report by Heinrich Haensel: Fabriken aetherischer Oele und Essenzen Pirna, Saxony, ... over the quarter ... , published between 1892 and 1910), extracts of which were published in specialist journals such as Apotheker Zeitung , the Central Pharmaceutical Hall and the Pharmazeutische Zeitung have been cited numerous times. These publications have contributed to making Haensel and its products known. The scientific character of these publications is due to Gustav Haensel. The description of the market environment for essential oils can also be found in these annual reports.

Offices

Haensel was also a member of various institutions (Chamber of Commerce, Chamber of Crafts and Trades, Railway Council, Chamber of Estates) and earned many merits and titles, including that of the " Secret Commerce Council ". Since December 1879 he was city councilor in Pirna (initially deputy) and since 1881 its head. He was made an honorary citizen on December 2, 1904 on the occasion of the 25th anniversary of his city council activities. In 1906 the non-profit Gustav Haensel Foundation was established in his honor.

During his long time as head of the city council, there were three mayors in Pirna.
